Is it true that scientists have never been able to cultivate Lichen in a lab? And that it essentially remains a mystery in terms of its component biology? I read it somewhere but never took the time to confirm that.

Scientists have been unable to successfully synthesize lichens in the lab using the algae and fungi that typically form those species. There are still some mysteries about the components – it’s definitely not as simple as the duality previously considered. Recent research has revealed that yeasts could be a big part of it, even bacteria. Actually, while making sure that I wasn’t just feeding you a bunch of lies I found this cool paper that looks into lichen’s bacterial association.
